"You have to go down the mine to understand!" Exploring the strange, fascinating world of the coal mine is an astonishing and educational experience. This genuine coal mine has been preserved as part of Belgium's industrial heritage.

Put on your jacket, adjust your helmet, and ride down the mining cage to discover the fascinating world of the "black-rock" galleries. Situated at -30 and -60 metres, they reveal the entire process of coal extraction.

Find out all about the interesting lives of the miners and their tough working conditions. See the technical equipment underground, the coal, the noisy machinery...
